1-7629. 2.3 yjz INVENTORS BY MX' ATTORNEY Patented Oct. 27, 1936 UNlTED' STATE-s OFFICE Our invention relates to that class of inven tions which are described in United States Let'- ters Patent No. 1,958,743, issued May 15, 1934, to R. L. Connor et al. This accounting deviceis designed to be usedto expedite the workof ac'- counting where it is desirable to carry a series of compilations across a number of columns-for the purpose of obtaining a total. Thedata to 'be totalled is usually placed upon pap'er'r'ibbons.

These ribbons are provided with a plurality of perforations at their tops so that they may be held upon pegs and they are generallymount ed in shingled relation. A movable line finder'is provided to guide the eye across the various columns. This in a large measure prevents-errors arising due to adding an amount in anotherflihe. Our invention has for its object to provide a mechanism for shifting the paper'instead 'of'the A further object is to provide for" shifting mechanism which will move the paper anexact distance, which distance may be predetermined;

In some cases it may be found desirable to -type or write the data WhlCh'iS to be totalled on every other line for greater legibility or any other de? sired reason.

A further object of our invention is to provide means whereby the shifting mechanism may be set so as to shift the. papers two lines ata time instead of a single line. 3

i The device which holds the paper, when'c'onstructed in accordance with our invention," is moved by means of a plurality of belts Whichare wound upon drums or pulleys rotated by the "shift-' 35 ing mechanism. Obviously if these belts'wei 'e permitted to overlap on the pulley or drums upon which they are wound, the resultant'eifect would be to increase the diameter of them by an am'ount equal to twice the thickness of the belts" and 40 would throw the shifting mechanism completely out of alinement. i

A further object is to so locatethewind 5;"

mechanism that it will automaticallyizomp'eri the paper ribbons have been attached to, {the clamping device and the ruled lines are slightly above or below the line finders to have means to overcome this difiiculty.

A further object of our invention is to provide,

a micrometer adjustment for the paper'with rela-' tion the line" finder "so as to move it either up "oiidown until the line finder registers precisely 'withthe' lines ruled on the paper.

Ourrneans of accomplishing the foregoing ob- 'jects may be more readily understood by having 5 reference toj the accompanying drawings, which are hereunto annexed and are. a part of this specification, in whichn Fig. 1 isafront evation'with a portion of the 1 papers torn away? 10 Fig; 2 is a" perspective view showing the paper partially lowered;- V e Fig. 3is a rear elevation with a portion of the covering brolg n away to show the interior constructiony'f' 15 Fig. 4; is; an 'end elevation;

Similar reference numerals refer to similar parts. throughout the entire description.

As shown inth e -drawings the perforated leaves or-ribb'oiis lare suspended from a clamping de- 3'5 vicebornprised of pegs 2. which are permanently attached t'o'a lower peg strip 3 and are covered byj'a lippe peg'jstrip 4. This upper peg strip maybe ,con' tedtothe lower peg strip 3 by w mesnsp s ap.jo .pushbuttons 5 such as are 40 eommonly usedtfoir attaching automobile curtains or an y other suitable or convenient manner for detachably securing the two peg strips to gether.

5 H "The. peg; strips :3 and 4 with the papers or ribbonstattachedaa-aresuspended fromthe pins 6 whichwareli. permanently fastened to terminal clips l x ilhese clips are attached-to the ends of belts 8. These belts 8 are connected to a cross strip'Bfwhichholds them in position. The peg strips} anagram the cross strip 9 are prevented fromdateral movement either to the right or left by the edges I07 of the peg board at uponwmcntiiepapers rest."

In order to conveniently remove the peg strips 3 and 4 together with the paper leaves or ribbons from the peg board, we cut or otherwise form thumb cuts ii!" in the edge of the peg board adjacent its upper end.

We provide a line finder strip H which has its ends permanently secured to the turned up edges Iii of the peg board by means of pivots I2 which permits it to :be swung away .from :the surface of the board t0. Y

The upper end of the peg board I is bent rearwardly on an approximate right angle for stiffening purpose. The ledge thus formed serves to provide a support upon which may be'fastened brackets 13 at the. :right and left sides thereof. These brackets 13 support .a shaft or rod 14. Upon the rod 14 are rotatably mounted idler pulleys i5 over which the belts 8 pass. In the base of each bracket I3'is a forwardly extending projection 68, the forward ends 50 of which .are bent downwardly to provide stops, the p rpose of which is to limit the extreme upward travel of cross piece 3 to prevent it from riding up over the idler pulleys IE5 and they also .serve to position'the peg strips ;3 and .4 in register with the thumb cuts IEJ" which are provided for the convenient removal of the paper clamping device from the pins 6.

The voperating .bar i6 is preferably cast or formed with a stud I1 (Figs...6'.1.) .upon which pivots a bearing plate l8. This bearing plate swings upon a shaft I9. This shaft I9 is arranged to extend beyond the full width of the device.' The shaft 39 is preferably supported at both ends in right and left hand walls 20 of the cover or casing which encloses the mechanism.

These end walls are spaced by means bf connecting rods .24 and are securely attached to the peg board by means of angle strips 21..

Rigidly fastened to the shaft-I9. is a ratchet wheel 2.2 and adjacent thereto are mounted the flanged driving pulleys .or drums 23, one being located at each side corresponding to the idler pulleys l5.

Normally, the operating bar I6 is retained in its upper position in contact with .astop pin 5! by means of a tension spring 21 which is located on therear end of'theoperating bar andopposite the pivot bearing l1. Spring 21 is attached to an arm 23 which is fixedly secured to a pivot 23 upon which is swingingly .mounted a ratchet v pawl 25.

' clockwise direction. The amount of movement is positively limited by engagement of the lower tooth 25" with' the but-t face of the teeth of the ratchet wheel 22. I

Means are provided to hold the pawl 25 in contact with the ratchet wheel 2.2 through the medium of a tension spring, one end of which is secured to .a pin 48 fixedly mounted in the pawl 25, the other end. being attached to a pinv 49 in the operating bar 16.

Means are provided for removable retention of the ratchet wheel 22 when thepawl 25 is lowered to engage in another tonth. These means comprise a small roller 31 which is held in contact with the teeth of the ratchet wheel 22 by means of a tension spring 32, The roller 3| is carried by a swinging arm 33 which is suitably attached to the frame plate l8. As illustrated it is secured on a pivot 34 mounted upon the said frame plate. One end of the spring 32 is attached to a pin 35 fixedly mounted in the swinging arm 33, its other end being secured to a pin 36 which is fixedly mounted in the lever 31.

Means for rotating the shaft 19 consist of a crank handle 38 fixedly attached at the extreme right hand projecting end of the shaft l9. This provides for the manual rotation of the ratchet wheel 22 and pulleys or drums 23, in either direction for the purpose of rapidly raising or lowering the papers a number of lines from the top or bottom or vice versa.

"I-o release the retention roll 3| and also the ratchet pawl 25 from engagement with the ratchet wheel 22, during this operation, we provide a-release lever 31 which is pivoted on a pivot or pin 45. A release knob 39 projects through a slot in the left hand wall 20 when it is removed to its extreme rearward position it engages a flat spring 40. This operates to force the rounded end of a detent pin 4| into a detent hole 42 formed in the bearing plate I8. Two other detent holes are provided, the purpose of which will be hereinafter explained. The lower terminal margin of the release .lever 31 is fashioned in the form of a cam which contacts with a roller 43 located .on the pin 35 being retained thereon by the end of the spring 32, the end being looped over the said pin 35. When the release lever 31 is moved by means of the knob 39 to the position illustrated in Fig. 7 the high part of the cam bearing on the roller 43 will actuate the arm 33 on its pivot 34 and cause the retention roller 3| to disengage with the teeth of the ratchet wheel 22. The release lever 31 is connected to the ratchet pawl 25 by means of a connecting link 44 which is pivoted on the stud 45 which is fixedly secured to the release lever 31. The opposite end of this link 44 is provided with a slot 46 through which passes a pin 48 to which the spring 41 is secured. This slot permits the movement of the pawl when it travels from the top to the bottom of the teeth in the ratchet wheel 22. It will be apparent from this description that movement of the release lever 31 towards the position indicated will cause the connecting link 44 to disengage pawl 25 from the teeth of the ratchet wheel 22.

Our means for providing the double line spacing comprise a detent hole 42 which is located directly under the pin 4| as shown in Fig. 6. In this position when the tension of the spring 21 draws the rear end of the operating bar downwardly the inside end of the slot 46 in the link 44 will move to a position which will permit the tension of the spring 41 to pull the tooth 25 of the pawl 25 into contact with the face of one of the teeth on the ratchet wheel 22, two spaces below the ratchet tooth contacted by the pawl tooth 25' when the rear end of the operating bar is in its upper position. This position of the pawl is indicated by means of dotted lines in Fig. 6.

In order to obtain single line spacing the release lever 31 is set in the intermediate hole 50 in which position the inner end of the slot 46 formed in the link 44 will prevent the upper tooth 25 of the pawl 25 from contacting the ratchet wheel although the operating bar I6 at this end will lower the same distance as when the double line spacing is desired. I As illustrated in Fig. 7 the pawl 25 is positionedto carry the second tooth whichgwillcontact 'onetooth below the extreme upperiposition. .Our means of providing for the micrometer adjustment to enable the operator to shift the position of the paper when the lines thereon do "not coincide with the line finder guide'is clearly seen in Figs. -6-and 7. When the paper ribbons have been secured to the clamping device it is mounted upon the pins 6, itmay be that when this is done, the ruled lines will be shown either slightly above or below the line finderguide II. This necessitates some means for adjusting the'paperminutely but accurately. Weaccomplish this in the following ay; I.

We provide a knob 52 suitably and fixedly attached to a shaft 53 which is mounted to rotate ina block 54. This block is rigidly attached to the side wall 29. r The shaft 53 is limited in end motion by means of collars 55- whioh are mounted each side of the block 54, the larger diameter of the shaft 53 is threaded into a swivel56 witha right hand thread. This swivel 5fi is provided with a neck or stem which passes through an opening formedin the bearingplate"l8 and is held in position by means of a nut as clearly seen in Fig. 9. Rotating the knob52 to the" right, therefore, causes the frame plate 18 and its assembled parts tomove around the shaft 19 toward the front of the device, and, because of the contact of the roller 3|, causes the ratchet wheel and pulleys to travel with it th us unwinding the belts and lowering the paper clamping strips by gravity over the faceof the'peg board. Obviously, the operation of the knob 52- in an opposite direction will wind the belts, thus elevating the paper assembly. e i e The operation of the device is asfollows: The distance which the paper moves under the line finder II with each downward stroke of the operating bar It is obviously governed by the number of teeth inthe ratchetwheel 22 together with thediameter ofthe winding pulleys or drums 23 and although this movement usually corresponds to the line ruling on the paper of six spaces of an inch it will be obvious to personsskilled in the art that movement'which will accommodate various other spaces may be readily obtained by substituting the ratchet whee1'22 or the pulleys 23 or both ofthem for othersofdifierent diameters and different numbersof teeth.

When the ribbons of paper lare of greater length than the circumferenceof winding drums 23 more than one turn of thesepulleys or drums 23 will be required to move the paper its entire length. Now if we were to permit the belts 8 to overlap after one complete turn of the pulley or drums 23 the working diameter of them would obviously be incerased to an amount equal to twice the thickness of the belts and consequently the alinement would be thrown out. We avoid this by locking the pulleys or drums 23 upon the shaft I9 in an offsetrelation to the idler pulleys I5. In this manner we produce at the rotation of the drums 23 a helical winding of the belts 8 and thus entirely prevent their overlapping regardless of the number of rotations. h

To prepare the papers for use on the peg board the lower peg strip 3 may be placed upon a suitable flat desk or table and the ribbons or-leaves of paper I are attached mamright to left in overlapping or shingled relation by'placing the upper perforated margin over the pins 2. The upper peg strip;,4: then placedover the paper and attached to thelower pegstripiby means of the snapbuttons 5. r 2: w' The release knob 39 isset temporarilyf'or release. and by. the rotation of the crank: 38 the cross piece 9 will be raised to the top of the peg board.: The. release knob is then set for either single or double spacing for the purpose only of engaging the retention roller 3| in the teeth:of the ratchet wheel. The line finder H is then swung upon itsi-pivots to an elevated position in. which position the paper may be freely passed under the line finder guide. The peg 'strips are hung from the pins 6 on the rightandleft hand sides of the peg boardand the paper strips are passed intermediate the line finder and the peg board"). The knob 39 is again set at release and the paper lowered bygravity or by operation of the crank handle 38. The release knob 39 is now set for the required single or double spacing and the top line of the paperis adjusted to the line finder guide II by operation of the bar i6 andtheknob52. 1
